Mitt Romney’s Iowa strategist is on his way to Florida – and he has rival Newt Gingrich squarely in his sights.

David Kochel said he intends to tell Florida voters about what he called Gingrich’s failure as U.S. House speaker, his work as a lobbyist on one of the largest spending bills in history, and “his unreliable leadership.”

“Newt finished a distant fourth in Iowa because voters came to know the real record behind his rhetoric,” he said in an email from the airport.

“You can’t attack Paul Ryan seated on a couch with Nancy Pelosi and call yourself a Reagan conservative,” added Kochel, a Republican from Des Moines. “It’s a sham, and when voters take a long look like they did in Iowa and New Hampshire, he finished fourth and fifth.”

Florida’s primary is a week away, on Jan. 31. Just four candidates remain in the GOP race – Romney, Gingrich, Ron Paul and Rick Santorum.
